    • A method for processing multiple Component Carriers (CCs) to be aggregated for transmission is provided in the present invention, the method comprising the steps of: acquiring a time domain signal of each of the multiple CCs; applying multiple fixed phase rotations respectively to the acquired time domain signal by utilizing phase rotation values in a set of phase rotations, so as to obtain multiple phase rotation versions of each CC; randomly selecting one of the multiple phase rotation versions of each CC to respectively constitute multiple candidate transmission groups, and acquiring an amplitude sum of the phase rotation versions for each of the multiple candidate transmission groups; determining a candidate transmission group having the minimum amplitude sum; and transmitting multiple phase rotation versions in the determined candidate transmission group having the minimum amplitude sum. The present invention substantively provides a general solution capable of minimizing CM/PAPR of aggregated CCs for UL and DL.
    • 本发明提供一种用于处理要聚合以发送的多个分量载波(CC)的方法,所述方法包括以下步骤:获取多个CC中的每一个的时域信号; 通过利用一组相位旋转中的相位旋转值对所获取的时域信号分别施加多个固定相位旋转,以获得每个CC的多个相位旋转版本; 随机选择每个CC的多个相位旋转版本中的一个,以分别构成多个候选传输组,并获取多个候选传输组中的每一个的相位旋转版本的幅度和; 确定具有最小幅度和的候选传输组; 以及在所确定的具有最小幅度和的候选传输组中发送多个相位旋转版本。 本发明实质上提供能够最小化用于UL和DL的聚合CC的CM / PAPR的通用解决方案。
